Answer 1

Sorry bro I don't know don't feel bab please

Answer 2

The correct option is (b) installing solar panels.

Solar panels are basically a source to generate electricity and there is no technological way to improve the air quality.

Thus, it cannot be used to purify air in anyway as it does not trap any dust particles from air, just the solar energy.

Electrostatic precipitators, composting and wind turbines contribute in purifying the air and improving its quality.
